Very easy install, probably a 3.
However bleeding the coolant system can be a bit tricky and could be a challenge for you, so that could be an 8 for you, best to follow the factory manual for the bleeding and you will eventually get there.
For sale are 4 x heavy duty preowned hydraulic wheel skates.
I used these for moving cars that I was dismantling around the shop
Just slip the skate into position and pump the foot pedal.
Very easy to use and very easy to move the car about.
More pictures available if required.

Cost £485.39.
Bargain price £200.00
Much will depend if at the end of the agreement you make the final balloon payment, use the car as equity as a deposit for another car, or simply hand the car back and walk away
Put 6 of these in the skip earlier today, shame as 4 were in great shape
I could not give them away as peeps did not want to pay the £10.00 shipping cost.
As you have discovered the electrics are different between the coupe and the roadster.
The roadster also have controls on the rear of the seat.
The roadster seats also have an auto electrical mechanism which slightly tilts the passenger seat when the roof is operated.
Best to swop like for like to save all the aggro.
The HR electrics are also different to the DE, as are UK model and JDM.
I am not saying that it can't be done, but there is no conversion kit for this as far as I know.
Any competent technician should be able to fit the HR clutch without any drama, however I would recommend a specialist as there are a few pitfalls.
Your potential supplier Tarmac are only 20 minutes from you.
